DAC088S085: How to recover from Power-Down Modes

Hi Yamaguchi,

Thank you for your query. I think writing zeroes with any of the 3 power-down commands mentioned in Table 1 should power up the channels. If you already have an EVM, can you please try this out? I will check with the internal team in the meanwhile to get an answer.

Hi Uttam,

Thank you for you reply.

I don't have an EVM, so could you check with your team?

Hi Uttam,

Thank you for your support. I understand that the recovery time would be 200us.

I also want to know how to recover from the power-down modes.

Hi Yamaguchi,

My apologies for the last post. I was supposed to post that on another thread.

Regarding your question, I am still waiting for a reply from the team.

Hi Yamaguchi,

This device being a very old part, I couldn't get a definitive answer from the team. The answer I got is that we can use one of the power down commands and make the corresponding DAC bits zero for powering up the channel. You can try this approach.

I have ordered the EVM for this. If you can provide me some time, I will be able to test it on the EVM and let you know.
